MANILA, Philippines (AP) -- Unlike many other Muslim royalties basking in grand palaces and opulent lifestyles, Sultan Jamalul Kiram III's kingdom sits in a rundown two-story house in a poor Islamic community in Manila, the only hint of power and glory the title attached to his name.
"I'm the poorest sultan in the world," the ailing Kiram, 74, told The Associated Press in an interview in his residence in Maharlika village in the Philippine capital.
Although largely forgotten and dismissed as a vestige from a bygone era, Kiram's sultanate, once based in the southern province of Sulu, has sparked the biggest security crisis in Malaysia and the Philippines in decades -- early last month, he sent his younger brother with about 200 followers, dozens of them armed, by boat from southern Philippines to a village in Sabah state in neighboring Malaysia to claim the land the sultanate insists belongs to them.
A stunned Malaysia, which runs the frontier resource-rich region of timberlands and palm oil plantations as its second-largest federal state, poured in elite police and army troops and called in airstrikes to quell what it saw as an armed intrusion.
After weeks of sporadic clashes that killed 19 intruders and eight policemen, troops launched a full-scale assault Tuesday, codenamed "Operation Sovereign," but failed to account for most of the Filipinos, who according to the Kiram family were unhurt.
Malaysian forces shot and possibly killed one of the men, who appear to be trying to escape the area, police said. Home Minister Hishammuddin Hussein said later Wednesday that security forces combing the area found 12 bodies. However, it was not clear if they died in Tuesday's strike or in the previous weeks of clashes.
The crisis has tested the neighbors' friendly ties and hit the leaders of both nations at a delicate time politically.
The Kirams claim Sabah has belonged to their sultanate for centuries and was only leased to Malaysia, which they say pays them a paltry annual rent of 5,300 Malaysian ringgit ($1,708). Malaysian officials contend the payments are part of an arrangement under which the sultanate has ceded the 74,000 square kilometers (28,000 square miles) of Sabah territory to their country.
Philippine presidents have relegated the volatile feud to the backburner despite efforts by the Kirams to put it back to the national agenda. The Feb. 9 Sabah expedition by the sultan's younger brother, Agbimuddin Kiram, and the ensuing violence have resurrected the long-dormant issue with the murky history beyond anybody's expectations.
One big obstacle for the Philippines is a number of the Kiram heirs, all claiming to be the rightful sultan. That put the government in a quandary on who to deal with for the Sabah claim to be pursued, historian Manolo Quezon IIII said.
Overrun by history, the Kirams carry royal titles and nothing much else.
"When I was a child, I thought 'princess' was just my name because when you're a child, your idea of being a princess is one with a crown, a palace, a carriage," said Jacel Kiram, a 35-year-old daughter of the sultan, who is regarded a princess.
At his Maharlika village home, the sultan, who has failed kidneys and a heart ailment, struggled with slurred speech to proudly recount the saga of his clan's empire based in the Sulu archipelago in the southern Philippines. Chinese and European leaders, he said, once sent vassals to pay homage to his powerful forebears. The Sulu sultanate, which emerged in the 1400s, preceded both the Philippine republic and Malaysia by centuries.
The exploits of the sultanate's native Tausug warriors were so legendary, the Brunei sultan at the time sought their help in putting down a rebellion in the 1600-1700s. When the uprising was crushed, the Brunei sultan handed over Sabah -- then part of Brunei -- to his Sulu counterpart as a gift of gratitude.
A Filipino sultan later leased Sabah to a British colonial-era company. The territory was later annexed by Britain. In 1963, six years after colonial Malaya gained independence, Sabah voted to join the new Malaysia.
The Sulu sultanate had steadily declined through the centuries, its power passed on to a succession of leaders and heirs. Jamalul Kiram III is the 33rd sultan and a symbolic leader with followers in Sulu and nearby southern provinces, which are among the country's poorest and are troubled by Muslim rebels, al-Qaida-linked extremists and outlaws.
Born in Sulu's far-flung Maimbung town in 1938, Kiram is a beloved leader who in his youth turned to dance and singing and played sports, including his favorite, tennis. He once worked as a disc jockey in a Jolo radio station. He took up law but failed to take the bar exams when he joined a prominent cultural dance group in the 1960s, according to his wife, Fatima Celia.
